ok st school we are working on a computer to changr it into a video editing machine,so far so good but we went to upgrade ram to a 512mb chip, acording to ibm it can handle it but when ever we put the chip in with the orgignal 128 it gives a beep code and this is the same beep code that happens when it is just the 512, tryed it in both slots, and the ram works in anouther computer. the beep code is that the onboard video card is not operational. it is a intel 810 video card. does anyone know what could be causing this and if puting in a simple pci video card and then the ram, totaly not using the onboard vid card?????
